Question

please tell what is the value of √ ​

Answer 1

Answer:

Like a mathematician the weird looking symbol √ is a device that takes some input and spits output. The input and output are of course numbers.

It is also know as the square root of the given input. Let's see how this device works. Basically, we can feed two types of number to this device either a positive real number or a negative real number.

• Working of this device when the input is a positive real number

In the beginning when this device was made, it was very happy working with the positive real numbers. Give the input and get a output. When a positive real number N is fed, the output given by the device is

$N \frac{1}{2}$

Observe some examples:

$1. Let \: us \: feed \: an \: easy \: one N=25N=25 then \: the \: output \: is 21\frac{1}{2} = {5}^{2} \times \frac{1}{2} = 5$

Now feed a difficult one N=1729. Well in this case, when a taxi number is fed, we have to use a calculator unless you are very good at calculations in your brain. Using calculator, we shall find it to be 41.5812458 upto 7 decimal places.

!!...Hope it's help you...!!

Answer 2

Answer:

A square root of a number is a value that, when multiplied by itself, gives the number. Example: 4 × 4 = 16, so a square root of 16 is 4. Note that (−4) × (−4) = 16 too, so −4 is also a square root of 16. The symbol is √ which always means the positive square root.
